I attach them using:
fglActiveTexture(GL_TEXTURE0+i);
glBindTexture(target,tex[i]);
fglFramebufferTexture2DEXT(GL_FRAMEBUFFER_EXT, 
       GL_COLOR_ATTACHMENT0_EXT+i, target, tex[i], 0);
So how do i unattach them ? I can't see it in the fbo spec nor on the tutorials on this site as I can't download the source code at the work pc. cheers

You mean detaching the texture attached to the color attachments, right? Have you tried

glFramebufferTexture2DEXT(GL_FRAMEBUFFER_EXT, GL_COLOR_ATTACHMENT0_EXT+i, target, 0, 0);

Passing 0 will detach the texture attached to the FBO.
